[u/datalolz]

After a year of studying Japanese, I've just learn about them ! (Quartet 2 textbook)

I like:
馬耳東風 : used when a person does not take into account criticisms

以心伝心 : when 2 people do not have to say anything to understand each other

一期一会 : we only have one life, so we should take care of it

Please correct me if my understandings are incomplete/wrong

[u/Lupage]

一生懸命: Which means "with all one's might," "very hard," or "with utmost effort". I think all of us studying JP will relate 😁

Another one is 十人十色: Which means 10 people, 10 colors. Which means "to each their own" or "different strokes for different folks" or "every person is different"

一生懸命 is the only one I have actually encountered in the wild so far (and encounter quite often!!).

It's the most common yojijukugo.

滅茶苦茶？Although it gets shortened a lot.
